SPECIFICATION DATA for EPMS...LSV Low Speed Valve (LSV) LSV Series hydraulic motors have been designed to operate with normal pressure drop and to ensure smooth run at low speed (up to min ), as the best security for operation is guaranteed at frequency of rotation min. They have an increased starting pressure drop and are not recommended for using at pressure less than 4 bars. Look at specification data for hydraulic motors standard version. The modification concerns only the following parameters : maximum speed, maximum output, maximum Oil flow and maximum starting pressure. EPMS EPMS EPMS 1 EPMS 16 EPMS EPMS EPMS 1 EPMS 4 Max.

Their main purpose is to operate as series-connected motors in hydraulic systems. For this version is permissible decreasing of the maximal torque with up to % (at middle speed) and up to % (at high speed) in comparison to the standard versions of motors.

DIMENSIONS AND MOUNTING DATA -EPMSB A B Actuating the brake level, the brake shaft is turned. The rectangular shape of the inner part of this shaft forces the brake pads to be pressed against the brake drum. This brakes the wheel or the winch drum. Releasing the level, the springs pull it and the brake pads back to the initial position. The motor output shaft is released. Minimum angle adjustment is. It can be adjusted by dismounting the level. Depending on the application You can choose the actuating direction of the brake level. The rod connection actuating the brake should be capable of moving at last mm from neutral to extreme position.
